Dry skin has high levels of resistance to electric current due to its low moisture content. The dry outer layer of the skin, primarily composed of keratin and lipids, acts as a barrier that inhibits the flow of electrical current. In electrical terms, resistance is the property that opposes the flow of electric charge, causing energy to be dissipated in the form of heat.

When the skin is dry, its resistance increases significantly compared to when it is moist. Moisture in the skin provides conductive ions that can facilitate electrical current flow, reducing resistance. Therefore, the high resistance of dry skin plays a crucial role in electrical safety, as it limits the amount of current that can pass through the body in case of accidental contact with live circuits.
